Organic bifunctional device and preparation method thereof

The invention discloses an organic bifunctional device and a preparation method thereof. The organic bifunctional device is composed of a transparent glass substrate, an anode layer, a hole transport layer, an exciton regulation and control layer, an active doping layer, an electron transport layer and a cathode layer. Under the driving of an external forward voltage, the organic dual-function device can realize an electroluminescent function, and under the driving of an external reverse voltage, the device can realize an ultraviolet detection function. The organic dual-function device has dual functions of electroluminescence and ultraviolet detection, and not only has the characteristics of high efficiency, ultra-thinness and integratability, but also is simple in preparation process, short in preparation time and low in cost. 本发明公开了一种有机双功能器件及其制备方法，有机双功能器件由透明玻璃衬底、阳极层、空穴传输层、激子调控层、活性掺杂层、电子传输层和阴极层构成。在外加正向电压的驱动下，该有机双功能器件能够实现电致发光功能，而在外加反向电压的驱动下，该器件可以实现紫外探测功能。该有机双功能器件同时具有电致发光与紫外探测的双重功能，不仅具有效率高、超薄、可集成的特点，而且制备工艺简单、
